8.2 Disabling the touch screen
Cleaning
You can clean the touch screen of the HMI device when it is switched on and a connection is
active. To do this you must disable the touch screen.
WARNING
Unintentional response
If you clean the touch screen while it is switched on, you could initiate operator controls by
mistake.
Switch off the device or - if running - clean the touch screen only when it is in the disabled
state! Note that the touch screen disable automatically ends after 15 seconds.
Procedure
To disable the touch screen, proceed as follows:
1.
Choose "Clean screen" in the Start menu in the taskbar.
After 15 seconds the disable automatically ends.
2. Clean the touch screen.
3. If you want to continue cleaning, choose "Clean screen" again in the Start menu.
8.3 Calibrating the touch screen
If the position touched on the touch screen during operation no longer agrees with the
position evaluated by the touch screen, the touch screen must be recalibrated.
Procedure
1. Choose "Calibrate" in the Start menu.
2. Start the calibration with the "Yes" button.
3. Touch the crosses displayed on the touch screen for several seconds, until the cross is
moved. Several measurements are performed in each case and averaged.
A corresponding message appears when the calibration is finished.
If the touch screen cannot be operated on account of an error during calibration, the
following options are available for restarting the calibration:
●
Using an external mouse to open the calibration on the device
● Restore to factory settings
